HOOKE'S LAW Introduction In physics, Hooke's Law is one of the fundamental principles governing how objects deform under external forces . Named after the 17th-century British physicist Robert Hooke, this law provides a crucial understanding of the behavior of elastic materials, such as springs and rubber bands. Whether stretching a rubber band or compressing a spring, Hooke's Law helps explain what happens when forces act on these materials. What is Hooke's Law: Hooke's Law states that the force F needed to extend or compress a spring by some distance x is proportional to that distance. Mathematically, it is expressed as: F= -kx Here k represents the spring constant, which is the measure of the stiffness of the spring, and x is the displacement from the displacement position. The negative sign indicates that the force exerted by the spring is in the opposite direction of the displacement. Understanding the Spring Constant: The spring constant k is a critical co...
Difference between Translatory, Rotatory and Vibratory Motion And Some basic Concept that define Motion
Difference Between Translatory, Rotatory and Vibratory Motion Some Basic Concepts that Define Motion Distance: The total length covered by a body without mentioning the direction, is called Distance. Its unit is Meter. It is Scalar Quantity. Displacement: The distance measured in a particular direction is said to be Displacement. Its Unit is Meter. It is a vector quantity. Speed: Speed of an object determines how fast the object is moving. The rate of change of the position of an object is called Speed. It is a Scalar quantity. Its Unit is meters/seconds. It can be calculated as: If the body covers equal distance in equal interval of time its speed is said to be Uniform Speed. If a body doesn't cover equal distance in equal interval of time, then its speed is said to be Variable Speed. Velocity: Velocity means the speed of an object in an specified direction. It is the rate of change of displacement with respect to time. It is a vector quantity. Its unit is meters/sec...
